Description
W szczególnosci dobre wyniki uzyskuje sie jesli proces termicznego odsiarczania prowadzony jest 20 25 30 w sposób ciagly lub periodyczny w elektrycznym piecu oporowym, którego rdzen oporowy stanowi wilgotny surowy koks naftowy o granulacji do 40 mm. Rdzen ten charakteryzuje sie takim sto¬ sunkiem przekroju do dlugosci, ze stosunek sred¬ nicy ekwiwalentnej rdzenia do jego dlugosci wy¬ nosi 1 : 3 do 1 : 10.Proces prowadzi sie tak by gestosci pradowe w rdzeniu miescily sie w zakresie 3—7 A/cm2 w strefie maksymalnej temperatury. Okres czasu przebywania koksu w tej strefie uzalezniony jest od zawartosci siarki w surowcu wstepnym lub wymagana zawartoscia siarki w produkcie kon¬ cowym i wynosi 2—5 h.Opisany w zgloszeniu proces zapewnia uzyska¬ nie kalcynowanego koksu naftowego o zawar¬ tosci siarki ponizej dopuszczalnej w przemysle elektrodowym normy, cechujacego sie niska opor¬ noscia wlasciwa i wysokim ciezarem rzeczywi¬ stym, przy czym jego wytrzymalosc mechaniczna jest nie nizsza niz uzyskiwana w tym samym za¬ kresie temperatur przy kalcynacji gazowej. PLIn particular, good results are obtained if the thermal desulphurization process is carried out continuously or batchwise in an electric resistance furnace, the resistance core of which is wet crude petroleum coke with a grain size of up to 40 mm. This core is characterized by such a cross-section to length ratio that the ratio of the core's equivalent diameter to its length is 1: 3 to 1:10. The process is carried out so that the current densities in the core are in the range of 3 to 7 A / cm2 in the maximum temperature zone. The residence time of coke in this zone depends on the sulfur content in the initial raw material or the required sulfur content in the final product, and amounts to 2 - 5 hours. The process described in the application provides for obtaining calcined petroleum coke with a sulfur content below the permissible standard electrode industry, characterized by low specific resistance and high real weight, and its mechanical strength is not lower than that obtained in the same temperature range by gas calcination.
